This bypass pipe 18 also allows for filling buffer container 1,2 via compressor 7.
The station 100 also includes the part 9,10 for being used to purify the hydrogen provided by the source in first end 4, and it is preferably located In the upstream of compressor 7.Purifying part preferably includes known relent pressure-variable adsorption (TPSA) separator, the separator Including one and preferred multiple adsorption beds.For example, and as illustrated, purifying part 9,10 includes parallel positioning in the line Two adsorption beds (zeolite or other).The gas provided by source 14 is alternately received into absorber 9,10 by valve system One then another in, absorber 9,10 alternate runs (one under conditions of high temperature and low pressure regenerate, while another Adsorbed under conditions of low temperature and high pressure).For example, it can be use molecular sieve or the TSA of activated carbon with coaxial bed Type.For the sake of simplifying accompanying drawing, do not show that the pressure for tank 9 and 10 declines or temperature rises and from an absorber to another One all valve for being transitioned into needed for production model (system is known per se).
Therefore, as illustrated, the circuit can include making the first adsorption bed 9 be connected to the second absorption by known way (vice versa, and another delivery pipe not shown in figure can connect two absorbers for simplicity for the delivery pipe 16 of bed 10 9th, 10 so as to perform opposite process).The delivery pipe 16 equipped with valve 22, the valve can control tank 10 regenerate pressure and Flow rate.Delivery pipe 16 is provided for making it possible to purging absorber 9 by the gas (hydrogen) from another absorber 10 (on the contrary It is as the same), so as to perform the elution step of absorber 10 in regeneration stage.
According to a favourable specific features, the station includes being used for from the gas compressed in compressor 7 to purification portion Part 9,10 optionally transmits the circuit 16,17 of heat.
If necessary, purifying part 9,10 can especially require interim reheating, such as TSA types are adsorbed in regeneration stage Device may need to reheat (temperature is for example between 200 to 300 DEG C).
As illustrated, this circuit 16,17 for being used for optionally transmission heat may include to be positioned at the exit of compressor 7 Heat exchanger 17, with hydrogen and on the other hand on the one hand the heat exchanger carry out heat exchange with (multiple) delivery pipe 16. That is, the purge gas from the first adsorption bed 9 carries out hot friendship before the second adsorption bed 10 is purged with compressed gas Change.So, the purge gas used in absorber 9,10 regenerative processes is reheated to improve the efficiency of adsorbent reactivation.
This allows to reheat it in the regeneration stage of absorber 9,10, while compressor 7 is left in cooling Gas.If it is necessary, except heat exchanger 17, circuit may include the supplement cooling exchanger 23 for cooling down compressed gas.Example Such as, the exchanger 23 is for example supplied to cryogenic fluid via water line 24.
Certainly, as modification or combination, the heat from compressed gas can be directly delivered in regeneration stage absorber 9, 10 (such as via different heat-transfer fluids).
It is, of course, preferable to install reheater 21, to supplement reheating during regenerating, (hydrogen is for example in the outlet of compressor 7 About 100 DEG C of temperature is reheated to, and regenerates and usually requires higher temperature, such as 200 DEG C).This extra reheating Device 21 can also be positioned in delivery pipe 6, connected with above-mentioned heat exchanger 17.
The recovery and utilization of the heat produced in above-mentioned compression process make it possible to reduce the reheating of additional reheater 21 Power.
As illustrated, the station 100 can also extraly include the selectivity for being supplied to the gas of tank 8 at delivery pipe 6 Cool down the system (such as hydrogen is cooled to the low temperature between -196 DEG C to -40 DEG C) of (i.e. controlled cooling).As illustrated, this is cold But can by carried out with circuit gas heat exchange the first cooling exchanger 3 and for low-temperature receiver 5 and first heat exchanger 3 it Between circulation heat transfer fluid loop 33 routinely carry out.Traditionally, this communication circuit 33 may include not show for simplicity The valve and/or pump shown.
Low-temperature receiver 5 may include following at least one：The deposit of liquefied gas such as nitrogen, the ethylene glycol of various mass concentrations is water-soluble Liquid, ammonia spirit, propane, or traditional refrigerant.
100 it can also be optionally included in before purifying step or process as shown in the region of dotted line limit, stood in figure In cold optionally transmitted between low-temperature receiver 5 and gas (optionally refer to preferably require strong to control according to refrigeration Degree).Therefore, the station 100 may include to exchange with the second cooling that the gas of the porch of purifying part 9,10 carries out heat exchange Device 13, and the loop 113 for the heat transfer fluid that circulated between low-temperature receiver 5 and second heat exchanger 3.
This of gas and/or purifying part 9,10 is cooled in by cleansing phase (gas enters absorber and adsorbing contaminant During) for purifying part, especially for temp.-changing adsorption (TSA) purifier efficiency it is particularly advantageous.
Therefore low-temperature receiver 5 can be shared in station 100/shared, to improve efficiency and improve component cost.
This framework ensure that the operation of the high-efficiency and economic at station 100.
The operation of packing station 100 may include two single stages.
In the first operation phase, (multiple) buffer container 1,2 can be filled.The Gaseous Hydrogen supplied by source 14 is in purification It is cleaned in part 9,10, is then compressed and be injected into buffer container 1,2.It is switched to from one in container 1,2 another Individual filling is performed when its nominal pressure (generally between 450 to 850 bars) can be reached in the pressure for the container 1,2 being filled. The filling of buffer container 1,2 can start when such as its internal pressure is less than threshold value (such as being respectively 350 and 700 bars).Institute Step is stated to be not necessarily continuously.During in the first stage, low-temperature receiver 5 cools down power to the supply of second heat exchanger 13.
In the second operation phase, one or some tanks 8 are filled by station 100.For example, tank 8 is filled to the pressure of 700 bars Power.Tank 8 is equalized successively with buffer container 1,2.From a switching to another of buffer container 1,2 can buffer container 1, Pressure difference between 2 and target tank 8 is performed when being less than predetermined threshold.According to the initial pressure in tank 8, pressure equalization step can be saved Slightly.In a known manner, if necessary, compressor 7 can improve or supplement the filling process.In this second stage phase Between, low-temperature receiver 5 cools down power to the supply of first heat exchanger 3.
As modification, if necessary, can optionally be set in the porch of compressor 7 heat exchanger (not shown) so as to Compressor can not allow to reheat the gas during cold gas.
The invention enables cost, overall dimensions and the energy expenditure for being likely to decrease packing station.
